The WiFi is runing great on all devices, including iPhones, Samsungs S6s, laptops, music devices etc. But on S7 will take 15 sec or more to load a web page. Also, some apps are very slow. Again, I updated the dlink router firmware, the wireless is supper strong in the house, I played with the router setup, went back to Best Buy they cleared the cache, basically did everything. Anyone has this type of issue? Additionally the battery is acting strange. My son is not very happy with this phone. Any help it is much appreciated!
